Lying is an important moral phenomenon that most people are affected by on a daily basis—be it in personal relationships, in political debates, or in the form of fake news. Nevertheless, surprisingly little is known about what actually constitutes a lie. According to the traditional definition of lying, a person lies if they explicitly express some...

Assertions are our standard communicative devices for sharing and acquiring information. Recent studies seemingly provide converging evidence that assertions are subject to a factive norm: you are entitled to make an assertion only if it is true. However, these studies assume that we can treat participants' judgements about what an agent ‘should sa...

Deceptive implicatures are a subtle communicative device for leading someone into a false belief. However, it is widely accepted that deceiving by means of deceptive implicature does not amount to lying. In this paper, we put this claim to the empirical test and present evidence that the traditional definition of lying might be too narrow to captur...

In times of what has been coined “post-truth politics,” people are regularly confronted with political actors who intentionally spread false or misleading information. The present article examines (a) to what extent partisans’ judgments of such behaviors as cases of lying are affected by whether the deceiving agent shares their partisanship (actual...

This handbook introduces readers to the emerging field of experimental jurisprudence, which applies new empirical methods to address fundamental philosophical questions in legal theory. The book features contributions from a global group of leading professors of law, philosophy, and psychology, covering a diverse range of topics such as criminal la...

There is an ongoing debate about whether rational or emotional appeals have a greater influence on moral behavior. The opportunity to donate to a charity provides an applied case to test this influence. Previous studies confirm the power of emotional appeals. For rational appeals, the results are mixed. We present the results of a pre-registered ex...

Previous research has shown that people judge sacrificing a few people to save a larger number to be morally permissible when the intervention targets the threat but not when it targets the victims. We investigated whether this distinction according to the locus of intervention influences people's evaluations of wartime scenarios and whether such e...

Large language models (LLMs) have taken centre stage in debates on Artificial Intelligence. Yet there remains a gap in how to assess LLMs' conformity to important human values. In this paper, we investigate whether state-of-the-art LLMs, GPT-4 and Claude~2.1 (Gemini Pro and LLAMA 2 did not generate valid results) are moral hypocrites. We employ two...

Misinformation plays an important role in our lives, be it lies told in everyday conversations or false information spread on social media websites. But when do people consider a statement to be false or an instance of lying, and do these judgements differ between cultures? In the present paper, we shed new light on these questions by examining to...

Does lying require objective falsity? Given that consistency with ordinary language is a desideratum of a philosophical definition of lying, empirical evidence plays an important role. A literature review reveals that studies employing a simple question-and-response format, such as “Did the speaker lie? [Yes/No]”, favour the subjective view of lyin...

Large language models have been used as the foundation of highly sophisticated artificial intelligences, capable of delivering human-like responses to probes about legal and moral issues. However, these models are unreliable guides to their own inner workings, and even the engineering teams behind their creation are unable to explain exactly how th...

We investigate the impact of informal arguments on judgments about thought experiment cases in light of Deutsch and Cappelen’s mischaracterization view, which claims that philosophers’ case judgments are primarily based on arguments and not intuitions. If arguments had no influence on case judgments, this would seriously challenge whether they are,...

In this paper we develop test cases to adjudicate between dual-process and the causal mapping explanations of order effects. Using dilemmas with minimized emotional force, we explore new conditions for order effects to occur. Overall, the results support causal model theory. We produced novel evidence that order effects extend not only to cases wit...

In this paper, we report the results of three high-powered replication studies in experimental philosophy, which bear on an alleged instability of folk philosophical intuitions: the purported susceptibility of epistemic intuitions about the Truetemp case (Lehrer, Theory of knowledge. Westview Press, Boulder, 1990) to order effects. Evidence for thi...

Theorists in the debate about how to define lying disagree whether it is possible to lie with pictures. At the same time, they agree that definitions of lying should be consistent with how laypersons use the term ‘lie’. This calls for an empirical perspective on whether ordinary usage allows for pictorial lies. The present paper provides some initi...

In this paper, we present and discuss the findings of two experiments about reference change. Cases of reference change have sometimes been invoked to challenge traditional versions of semantic externalism, but the relevant cases have never been tested empirically. The experiments we have conducted use variants of the famous Twin Earth scenario to...

Does lying require a speaker to explicitly express something (she believes to be) false, or is it also possible to lie with deceptive implicatures? Given that consistency with ordinary language is a desideratum of any philosophical definition of lying, several studies have addressed this question empirically in recent years. Their findings, however...

We conducted two experiments to see whether common folks think that the so-called telltale sign bald-faced lies are intended to deceive-since they have not been tested before. These lies involve telltale signs (e.g. blushing) that show that the speaker is lying. Our study was designed to avoid problems earlier studies raise (these studies focus on...

Consider the following case: Dennis is going to Paul’s party tonight. He has a long day of work ahead of him before that, but he is very excited and can’t wait to get there. Dennis’s annoying friend Rebecca comes up to him and starts talking about the party. Dennis is fairly sure that Rebecca won’t go unless she thinks he’s going, too. Rebecca: Are...

The first reference on rationality that integrates accounts from psychology and philosophy, covering descriptive and normative theories from both disciplines. Both analytic philosophy and cognitive psychology have made dramatic advances in understanding rationality, but there has been little interaction between the disciplines. This volume offers t...

In several recent papers and a monograph, Andreas Stokke argues that questions can be misleading, but that they cannot be lies. The aim of this paper is to show that ordinary speakers disagree. We show that ordinary speakers judge certain kinds of insincere questions to be lies, namely questions carrying a believed false presupposition the speaker...

The present study examines cross-cultural differences in people’s concept of lying with regard to the question of whether lying requires an agent to say something they believe to be false. While prominent philosophical views maintain that lying entails that a person explicitly expresses a believed-false claim, recent research suggests that people’s...

According to the subjective view of lying, speakers can lie by asserting a true proposition, as long as they believe this proposition to be false. This view contrasts with the objective view, according to which lying requires the actual falsity of the proposition asserted. The aim of this paper is to draw attention to pairs of assertions that diffe...

The question of how people hold others responsible has motivated decades of theorizing and empirical work. In this paper, we develop and test a computational model that bridges the gap between broad but qualitative framework theories, and quantitative but narrow models. In our model, responsibility judgments are the result of two cognitive processe...

According to the ‘expertise defence’, experimental findings suggesting that intuitive judgments about hypothetical cases are influenced by philosophically irrelevant factors do not undermine their evidential use in (moral) philosophy. This defence assumes that philosophical experts are unlikely to be influenced by irrelevant factors. We discuss rel...

Indifferent lies have been proposed as a counterexample to the claim that lying requires an intention to deceive. In indifferent lies, the speaker says something she believes to be false (in a truth-warranting context) but does not really care about whether the addressee believes what she says. Krstić (2019) argues that in such cases, the speaker d...

In the ‘push-dilemma,’ a train is about to run over several people and can only be stopped by pushing a heavy person onto the tracks. Most lay people and moral philosophers consider the ‘push-option,’ i.e., pushing the heavy person, as morally wrong. Peter Unger (1992, 1996) suggested that adding irrelevant options to the push-dilemma would overtur...

How do people hold others responsible for their actions? In this paper, we test and extend a computational framework originally introduced by Gerstenberg et al. (2018) that assigns responsibility as a function of two factors: a dispositional inference that captures what we learn about a person's character from their action, and the causal role that...

The field of moral psychology has become increasingly popular in recent years. In this chapter, we focus on two interrelated questions. First, how do peoplemake moral judgments? We address this question by reviewing the most prominent theories in moral psychology that aim to characterize, explain and predict people’s moral judgments. Second, how sh...

Lying is a familiar and important concept for virtually all of us, and philosophers have written a lot about what it means to lie. Although it is commonly accepted that an adequate definition of lying captures people's use and understanding of this concept, there have been surprisingly few empirical studies on it. n recent years, however, there is...

Empirical studies on moral dilemmas in which the principle of saving other people's lives conflicts with the prohibition on killing have shown that people consider harm more permissible when it is a side effect of a good action than when it is a means to a good end (Cushman & Young, 2011; Mikhail, 2011; Waldmann, Wiegmann, & Nagel, 2017). These jud...

Lying is an everyday moral phenomenon about which philosophers havewritten a lot. Not only the moral status of lying has been intensively discussed butalso what it means to lie in the first place. Perhaps the most important criterion foran adequate definition of lying is that it fits with people’s understanding and use ofthis concept. In this light...

In the so-called push dilemma, an out-of-control speed-train is about to run over five people and can only be stopped by pushing a heavy person onto the tracks. Most lay people and moral philosophers consider it morally wrong to kill the heavy person. Unger (1992, 1996), however, argued that adding irrelevant options to the push dilemma would overt...

Is it possible to lie despite not saying anyhing false? While the spontaneous answer seems to be 'no', there is some evidence from ordinary language that a lie does not require what is said to be believed-false. In this paper, we will argue for a pragmatic extension of the standard definition of lying. More specifically, we will present three exper...

Can a question be a lie? Theorists in the debate on how to define lying tend to answer this question negatively. They hold that questions can be misleading, but that they cannot be lies. The aim of this paper is to show that ordinary speakers disagree. With the help of three experiments, we show that ordinary speakers judge certain insincere questi...

According to epistemic closure, if someone knows some proposition P and also knows that P entails Q, she knows Q as well. This is often defended by appealing to its intuitiveness. Only recently, however, was epistemic closure put to the empirical test: Turri ran experiments in which closure is violated in folk knowledge ascriptions surprisingly oft...

The ‘Ought implies can’ principle (OIC) states that if you lack the ability to do X, then you are not morally obligated to do X. While philosophers believed it to be both normatively adequate and intuitively compelling, recent empirical findings suggest that laypeople reject OIC. In this paper, we suggest a pragmatically grounded model of the relat...

In this review we make a simple theoretical argument which is that for theory development, computational modeling, and general frameworks for understanding moral psychology researchers should build on domain-general principles from reasoning, judgment, and decision-making research. Our approach is radical with respect to typical models that exist i...

According to the epistemic closure principle, if someone knows some proposition P and also knows that P entails Q, she knows Q as well. This principle is often defended by appealing to its intuitiveness. But only recently was epistemic closure put to the empirical test: Turri ran experiments in which closure is (allegedly) violated in folk knowledg...

According to the traditional definition of lying, somebody lies if he or she makes a believed-false statement with the intention to deceive. The traditional definition has recently been challenged by non-deceptionists who use bald-faced lies to underpin their view that the intention to deceive is no necessary condition for lying. We conducted two e...

Most theories of moral judgments distinguish between acts and outcomes. According to these theories, moral judgments are either primarily based on the evaluation of the acts or the outcomes with multi-system theories allowing for both possibilities. Here we argue that it is not only the acts and outcomes that determine moral evaluations but also th...

Experimental restrictionists have challenged philosophers’ reliance on intuitions about thought experiment cases based on experimental findings. According to the expertise defense, only the intuitions of philosophical experts count—yet the bulk of experimental philosophy consists in studies with lay people. In this paper, we argue that direct (expe...

In this article, it is argued that empirical data can undermine normative arguments generated by intuitionist methodologies that involve a step of inducing an abstract principle from a set of case-based moral intuitions. The use of case-based intuitions in normative theory construction is conceptualized here as an inductive inference procedure in w...

Trolley dilemmas are widely used to elicit moral intuitions. Most people do not think it would be morally right to push a heavy man from a bridge, thereby killing him, in order to avoid the death of several other people. Here we empirically tested a prediction by Unger (1996) who claims that adding more options to this scenario would shift people's...

Explaining moral intuitions is one of the hot topics of recent cognitive science. In the present article we focus on a factor that attracted surprisingly little attention so far, namely the temporal order in which moral scenarios are presented. We argue that previous research points to a systematic pattern of order effects that has been overlooked...

The past decade has seen a renewed interest in moral psychology. A unique feature of the present endeavor is its unprecedented interdisciplinarity. For the first time, cognitive, social, and developmental psychologists, neuroscientists, experimental philosophers, evolutionary biologists, and anthropologists collaborate to study the same or overlapp...

In recent years, a number of philosophers have conducted empirical studies that survey people's intuitions about various subject matters in philosophy. Some have found that intuitions vary accordingly to seemingly irrelevant facts: facts about who is considering the hypothetical case, the presence or absence of certain kinds of content, or the cont...
